System overview
5.1 What is the SIMATIC ET200SP distributed I/O system?
Area of application
Thanks to its multifunctionality, the SIMATIC ET 200SP distributed I/O system is suitable for a
wide range of applications. Its scalable design allows you to tailor your configuration to local
requirements. Various CPUs/interface modules are available for connection to PROFINET IO,
PROFIBUS DP, EtherNet/IP or Modbus TCP.
SIMATIC ET 200SP with CPU allows intelligent pre-processing to relieve the higher-level
controller. The CPU can also be used as standalone device.
By using fail-safe CPUs, you can implement applications for safety engineering. Configuration
and programming of your safety program takes place the same way as for standard CPUs.
An extensive range of I/O modules extends the area of application of the ET 200SP system.
SIMATIC ET200SP is designed with degree of protection IP20 and is intended for installation
in a control cabinet.
With use of an ET 200SP R1, you increase the availability of the system through redundant
interface modules.
Configuration
The SIMATIC ET200SP distributed I/O system is installed on a mounting rail. It consists of:
•
CPU/interface module
•
Up to 64I/O modules, which can be plugged into BaseUnits in any combination
•
Up to 31motor starters
•
A server module that completes the configuration of the ET200SP.

System overview
5.1 What is the SIMATIC ET200SP distributed I/O system?
5.2 What are fail-safe automation systems and fail-safe modules?
Fail-safe automation systems
Fail-safe automation systems (F-systems) are used in systems with higher safety
requirements. F-systems control processes and ensure that they are in a safe state
immediately after shutdown. In other words, F-systems control processes in which an
immediate shutdown does not endanger persons or the environment.
Safety Integrated
Safety Integrated is the integrated safety concept for automation and drive technology from
Siemens.
Proven technologies and systems from automation technology are used for safety systems.
Safety Integrated includes the complete safety sequence, ranging from sensor, actuator and
fail-safe modules right through to the controller, including safety-related communication via
standard fieldbuses. Drives and controllers handle safety tasks in addition to their actual
functions.
Fail-safe modules
The key difference between fail-safe modules (F-modules) and standard modules is that they
have an internal two-channel design. This means the two integrated processors monitor each
other, automatically test the input and output circuits, and switch the fail-safe module to a
safe state in the event of a fault.
The F-CPU communicates with a fail-safe module via the safety-related PROFIsafe bus profile.
Fail-safe motor starters
Fail-safe motor starters enable safety-related tripping of motor loads. Fail-safe motor starters
are not PROFIsafe nodes. Motor starters operate together with the fail-safe modules of the
ET 200SP system.
Area of application of ET200SP with fail-safe I/O modules
By using the ET200SP distributed I/O system with fail-safe I/O modules, you are replacing
conventional safety engineering configurations. This includes the replacement of switching
devices for emergency STOP, protective door monitors, two-hand operation, etc.

SIMATIC Safety F-system with ET200SP
The figure below shows an example of a configuration for a SIMATIC Safety F-system with
ET200SP distributed I/O system and PROFINETIO. You can configure the PROFINETIO lines
with copper cable, fiber-optic cable or WLAN.
Fail-safe I/O modules and non-fail-safe I/O modules can be combined in an ET200SP
configuration.
The fail-safe IO controller (F-CPU) exchanges safety-related and non-safety-related data with
fail-safe and non-fail-safe ET200SP modules.

safety-related tripping of the load voltage for non-fail-safe output modules.
•
Fail-safe digital input modules detect the signal states of safety-related sensors and send
the relevant safety frames to the F-CPU.
•
Fail-safe digital output modules are suitable for safety-related shutdown procedures with
short circuit and cross-circuit protection up to the actuator.

PotDis-BaseUnit potential
distributor module
You use the potential distributor module to dis
tribute a variety of potentials (P1, P2). This allows
you to implement a multi-cable connection
without external terminals with 16-channel digital
modules.
The assembly has two parts:
• If you need additional potential terminals, plug
a PotDis-TerminalBlock in the PotDis-BaseUnit.
• Alternatively, plug a BU cover (15mm) on the
PotDis-BaseUnit.
With potential distributor modules, you may only
connect to the PotDis-TB versions BR-W and n.c.-G
potential, which exceed the voltage level of
SELV/PELV. Other SELV/PELV potential groups
should be separated with light-colored PotDis BUs.
Suitable PotDis-BaseUnits are available in each
case for the different requirements. You can find
additional information in section Selecting a
PotDis-BaseUnit (Page 90).
PotDis-TerminalBlock If you need additional potential terminals for a
PotDis-BaseUnit, plug a PotDis-TerminalBlock in
the PotDis-BaseUnit.
Voltages greater than SELV/PELV are only permit
ted for the PO PotDis-TBs BR (bridged) and NC (not
connected). The same applies to PE. Voltages at
the terminals of the PotDis modules connected to
the P1/P2 rails must not be greater than
SELV/PELV.
Suitable PotDis-TerminalBlocks are available in
each case for the different requirements. You can
find additional information in section Selecting a

3DI/LC module The optional 3DI/LC module has three digital
inputs and one LC input. For reasons of opera
tional safety, input LC is permanently set to
manual local mode. By parameterizing the
inputs DI1 - DI3 with motor CLOCKWISE or
motor COUNTER-CLOCKWISE, you can control
the motor in manual local mode.
The functions of the 3DI/LC module are not rel
evant to functional safety.
Detailed information on the functions when
using a 3DI/LC module can be found in the
Manual
(https://support.industry.siemens.
com/cs/ww/en/view/109479973).

Overview
The BaseUnits (BU) are classified according to different types. Every BaseUnit type is
distinguished by characteristics that match certain I/O modules and motor starters (see the
following table and graphics).
You recognize the BU type for an I/O module by the last two digits of an I/O module's article
number.
The BU type onto which you can plug the respective I/O module is printed on the I/O modules.
You can therefore read which BU type you need straight from the I/O module (see Factory
labels (Page 171) (page 122)).
Example: On the output module DQ16x24VDC/0.5AST with article number
6ES7132-6BH01-0BA0 the information "BU: A0" is printed. This means you can plug this I/O
module into a BaseUnit of BU type "A0", which means any BaseUnit whose article number
ends in "A0". I/O modules that are suitable for two BU types are labeled accordingly, for
example "BU: A0, A1".
NOTE
You will find a complete module overview of the ET 200SP distributed I/O system and an
overview of possibilities of combining BaseUnits and I/O modules/motor starters in the
Product information for documentation of the ET 200SP distributed I/O system
(https://support.industry.siemens.com/cs/de/de/view/73021864/en).
NOTE
Use of Ex modules
If you are using Ex I/O modules for the connection of intrinsically safe devices from Zone 0 or
Zone 1 in the ET 200SP configuration, observe the information for plant planning in the
System Manual ET200SPHA Distributed I/O system / ET200SP Modules for devices used in an
explosion hazardous environment
